When bed bugs hit my guest room (worst week ever), I realized choosing the right company is everything. I compared three companies, and the one I chose actually walked me through prep steps on the phone before I even booked. That level of effort told me they were serious. After booking, I had to modify the service date because of travel, and calling them got it fixed immediately. Look for companies that explain treatments clearly, offer guarantees, and have quick customer support. That “can I talk to a real human fast?” test became my deciding factor.
